global problem with passwords for MySql

I just have some problems, I can't open MySQL database and second problem PHPMyAdmin not work... after many tries I found problem was simple - password contain characters which MySQL can't accept (I don't know which exactly but must be some from these @#$%&()=-\/<>

My request is, can next version of cPanel check format of password and don't allow set passwords for MySQL databases which MySQL can't handle?

PHPMyAdmin has also problem because general cPanel password contain some characters, but cPanel had no problems accept this password.
